55 In said drawings III designates the boiler as a whole which is shown comprising a series of transverse sections including a front section II,

a back section I2, and a plurality of intermediate sections I3, which are communicatively connected at their upper corners by large nipples I4, and at l5 their diagonally opposite lower corners by smaller nipples I5. The sections II, I2 and I3 are provided on their opposite faces with peripheral beads IIa, I2a, ISE, and. interior beads IIb, I2b, I3b, p respectively, and are secured in assembled rela- 10 tion by tie rods |011.

The said sections I I, I2, I3 are essentially rectangular in form and each provided with a depending portion I6' at one of its lower corners With openings in which the lower nipples I5 are l5 fitted. The interior of said depending portions I6 together with the nipples I5 secured therein form a mud drum I1. The opposite lower corners of the assembled sections are supported in raised position by two or more legs or standards 20 I8.

The front section II is provided at one side adjacent to its lower end with a circular fuel opening I9 provided with a closure 20 secured in position by bolts 2|. The closure 2G is pro- 25 vided with a central aperture 22 adapted to receive the nozzle of an oil burner. The front section is also provided at its opposite side on about the same horizontal plane with the fuel opening I9 with a vertical clean-out opening 25 having a 30 closure 26 which is secured in position over said opening 2'5 by latches2'I pivotally secured to the front section.

Each intermediate section has a large circular opening 28 adjacent to one of its sides occupying 35 the greater part of the section and registering with corresponding openings 28 of the other intermediate sections, and with the recess 28aL in the back section I2, and With the opening I9 in the front section to form the longitudinal, cylinim drical fuel receptacle and combustion chamber 29 which is preferably provided with a refractory lining 29a. The openings 2B of the intermediate sections are enclosed at their opposite sides with registering hollow segmental, water-backed wall portions 30, 3I which merge at their lower ends with the water-backed horizontal base member 32, and at their upper ends with the relatively deep dome yportion 33 which extends entirely across the upper portion of the boiler.

At the side of each of said intermediate sections between the curved wall portion 3| of the fuel receptacle and combustion chamber and the vertical peripheralwater leg 34 is a vertical flue opening substantially coextensive in height of the fuel receptacle and combustion chamber 28, having a central vertical water leg 35 therein communicating at its upper end with the dome portion 33, and at its lower end with the depending mud drum portion I1. The said water leg 35 registers with the corresponding water legs of adjoining intermediate sections, and the member 35a of the back section I2, and forms jointly therewith a longitudinal partition serving to divide said vertical flue opening into a forwardly extending ue 36 and a rearwardly extending ue 31 which latter communicates at its outlet end with the registering smoke outlet opening 38 in the back section I2. I

The ilues 36 and 31 register at their forward ends with the clean-out opening'25 in the front section II, and are provided upon their vertical and horizontal wall portions with fins or extended surface members 39 which cooperate with those of the adjoining sections and form longitudinal baiiles to insure the eiicient distribution of the hot gases and products of combustion throughout said flues, and the maximum abstraction of the heat thereby.

The back section I2 is provided upon its inner wall at the junction of the fuel receptacle and combustion chamber with the intake end of the flue 36 with a series of radial ribs 40 arranged in the arc of a circle whereby the hot gases and products of combustion produced or liberated in the combustion chamberwill be deflected in their passage and caused to flare or spread so that the same will, upon entering the intake end of the flue 36, completely ll the same from top to bottom, and continue so through the ilues 36 and 31 to the smoke outlet 38.

Upon the outer wall of the back section I2, directly over the smoke outlet 38 is bolted a smoke hood 46 comprising a tubular portion 4.1 communicating with the upper portion of the smoke outlet 38, and a tapering pouch portion 48 depending from said tubular portion 41 communieating with the lower portion of said smoke outlet 38. The tubular portion 41 is provided with a reduced free end 49 adapted for attachment to a smoke pipe or stack.

The back section I2 is provided in its rear or outer wall portion with a cut-out portion 50 over which is disposed a semi-cylindrical cover 5I secured in place by bolts 52. The said cut out portion 56 and its cover 5I form a receptacle or casing for a hot-water coil or heater having one end connected to the intake pipe 53 communicating with a source of cold water supply, and to its other end connected to the outlet pipe 54 communicating through the pipe 62 with the hot water supply tank 6I.

The said rear wall is also provided with a smaller cut-out portion 55 to receive a water control device, not shown, over which is disposed a recessed cover 56 having an aperature 56a therein for connection with the source of water supply of the boiler. The said cover is secured in position by bolts 51. The said cut-out portion 55 and its cover 56 form a receptacle or casing to accommodate an automatic device for controlling the supply of water to the boiler.

The back section I2 is provided at its top with an outlet or ow nozzle 58 adapted to be connected to the supply line of the heating system, and at its opposite lower end said back section is provided with return inlet I6a adapted to be connected to the return line extending from the heating system.

The back section I2 is further provided centrally with respect to the fuel receptacle and combustion chamber 29 with an aperture 59 normally closed by a cover 60 through which the operation of the oil burner may be observed.

'Ihe front section II and the back section I2 are provided at their upper ends adjacent to one of their vertical surface and about midway between their opposite vertical surfaces with upwardly extending projections IIC, I2c forming saddles between which is supported a hot water supply tank 6I. The pipe 62 connects the coil of the hot water heater contained within the cut out portion or compartment 50 of the back section I2 with the intake port of the hot water supply tank 6I. Ihe hot water supply tank is provided at its top with an outlet pipe 63 leading to the ultimate discharge valves or faucets, not shown, and with a circulating pipe 64 communicating with the cold water intake pipe.

The boiler and hot water supply tank are preferably enclosed in a sheet metal jacket 64', having an opening 65 in its front of sulicient size to allow free access to the fuel receptacle and combustion chamber 29, and the fiues 36 and 31. The said opening 65 is provided with a closure panel 66 held in place at its lower edge by clips 61, and at its upper edge by fastening devices 68. Both the clips 61 and fastening devices 68 are engageable with the inner side of the jacket front along the edges of said opening. Above said opening 65 the jacket front is provided with smaller openings 69 and 10 for the indicating devices, and water gage glass respectively. The jacket back and the top are also provided with suitable openings for the smoke hood 46, ow and return connections 58, I6a, and other devices and parts, as required.
